User manual MAGELLAN GPS COMPANION

[. . . ] Welcome Thank you for your purchase of the Magellan GPS Companion and Map Companion CD. With the GPS Companion attached, your PalmTM OS Handheld Organizer becomes a complete travel tool that will not only save you time but completely removes the phrase "Where am I?" from your vocabulary. No matter where you go or what you do, the GPS Companion and your Palm organizer will provide you with all the information you need to get you where you are going. Using GPS Companion with Palm V/ Vx Series of Handhelds Using GPS Companion with Handspring Visor WARNING Driver shall not use this device while operating a vehicle to assist the driver to navigate.

[. . . ] (From 1 to 32) (Azimuth) The horizontal angle the satellite makes with respect to true North from your position. (From 0 to 359) (Elevation) The vertical angle of elevation the satellite makes with respect to your present position. (From 0 to 90) (Signal-to-noise Ratio) The incoming signal strength of the satellite signal measured in decibels. (Used-in-position) Checked if the satellite is being used to calculate your position fix. The Sky Chart Screen The Sky Chart Screen shows the position of the satellites in the sky relative to your present position. Your present position is displayed at the center of the concentric circles. The circles mark the 0, 30, 60 and 90 degree horizontal elevations of the satellite. The outermost circle also represents the azimuth angle, where 0 degrees is true North. Satellite values are shown in black for those satellites that are being tracked to compute your position fix. GPS Window Select Tapping here brings up a menu that allows you to select the different GPS screens to view. Position Fix Indicator This area indicates the current status of the position fix that is being computed: No Fix: 2D: 3D: Present position is not being computed. In a 2D position fix, altitude is not computed and the last computed or entered altitude is used. In a 3D position fix, altitude is being computed by the GPS receiver. Levels of position fixes are influenced greatly by how well the GPS Companion "sees " the satellites. For more information on getting good satellite signals see Tips on Satellite Signal Reception. Receiver Type The receiver type for the Map Companion software is "Magellan". Position Data During the initialization process, Lat/Lon (Latitude/Longitude) information is input here. After computing a position fix, the Lat/Lon of the computed fix is displayed. If the position fix is 3D then the altitude is computed by the Map Companion. If the last fix was 2D, then the altitude displayed is the last computed or entered altitude. GPS Time Data GPS time is extremely accurate as the time the satellites send to the GPS Companion is taken from the atomic clocks on the satellites. However, the time transmitted is GMT (Greenwich Mean Time) and requires an offset to adjust it to your local time. This offset and DST (Daylight Savings Time) flag are set during initialization but can be changed at any time. GPS Interval GPS Interval is adjusts the rate that the Navigation, Satellite and Sky Chart screens are updated. GPS Messaging This window displays the string of NMEA data that is received to your Palm organizer from the Map Companion. Start GPS This button starts the GPS communication between GPS Companion and the Map Companion. It is used only if the Stop button has been pressed. Stop GPS This button stops the GPS communication between the GPS Companion and the Map Companion software. Set Time The Set Time button sets your Palm organizer's time & date to that received in the satellite signals. Note: The GMT deviation and DST must be set correctly for this to work properly. Initializing the GPS Since the satellites are constantly rotating the earth, the GPS Companion wants to know approximately where it is located, the date and the time. This information isn't mandatory, the GPS Companion can "poll" the sky looking for satellites and eventually get the information it needs but this takes time. So to speed up this process the GPS Companion has a built in almanac of all the satellites and where they will be at any given time for all positions. So now with the approximate location and time, the GPS Companion just refers to its almanac and can immediately begin receiving satellite data. Well, every time the GPS Companion computes a fix it is stored in memory. [. . . ] In order to beam ALL waypoints or routes, tap the menu icon on your Palm organizer while the foreground screen is other than Waypoints or Route. From the Tools menu, tap on "Beam All Waypoints" or "Beam All Routes". Tap on the Applications Icon and point the IR port at the Palm organizer that is sending the data. You have the option to accept or not the received waypoint(s) or route(s). 2. 3. If you have any problems beaming the data, consult your Palm organizer user manual. Accessing Help Help files are available for screens in the NAV Companion. [. . . ]
